This order comprised 20 pieces of 6-layer flexible PCBs, each measuring 86 × 112 mm with an overall thickness of 0.23 mm using rolled copper. The design required 4/4 mil trace and spacing, 0.15 mm minimum holes, yellow soldermask, white silkscreen, and immersion gold ENIG finish. These parameters demanded exact material handling and registration control throughout the multilayer stack.
Production followed a sequence of polyimide material preparation, inner layer imaging, circuit etching, high-pressure lamination, and coverlay application tailored to the thin construction. Solder mask application on the flexible substrate was followed by electroless nickel and immersion gold deposition under tightly controlled parameters to maintain surface uniformity and plating adhesion. No stiffeners were added, preserving the required bend characteristics.
Dynamic flex testing and 100% electrical testing confirmed circuit continuity and mechanical endurance after 18.9 days of manufacturing. The resulting boards delivered consistent performance meeting the tight geometry and flexibility demands of the original specification.
